How to Improve the Predictive Value of Preclinical Oncology Studies: Imaging Orthotopic Models
Standard oncology tumor models are implanted subcutaneously. However, there are growing concerns around subcutaneous models and their predictive value due to the lack of an organ-specific tumor microenvironment (TME). This is particularly important for I/O studies, as immunotherapy response is heavily dependent on the TME.
Orthotopic models provide a more predictive alternative, allowing establishment of a relevant organ-specific TME, as well as clinically-relevant tumor metastasis. To realize the full benefits of orthotopic metastatic modeling, disease needs to be tracked and monitored in real time, which is enabled by preclinical optical imaging.
This White Paper explores the main benefits of imaging orthotopic, metastatic models. Model key utilities are explored for studying disease progression and assessing novel agents and combinations for each stage of disease.
Download This White Paper to Understand:
- How orthotopic models allow establishment of a relevant tumor niche, as well as spontaneous metastasis, enabling assessment of treatments targeting metastases
- How to model late-stage disease when spontaneous metastasis occurs at a low incidence e.g. bone metastases, through experimental metastasis models
- How to use experimental models to recapitulate difficult to treat metastatic sites such as brain, and evaluate agents crossing the blood brain barrier
